'o allvwwm it may concern:

`4'Beit k own that I, ROY M. Jn'rr, a citizen of thel U1 i ted States, residing at'Greenville, in ftheeountyi of Bond, State of illinoisU have invented certain new and useful' Linprovements L Iro'nsandl 'do hereby declare'the followto self-heating copper soldering point of the device.

. 'die The invention resides in a novel fuel supply pipewhich embraces the burner nozzle so that the fuel is tion consists of lcertain novel details'of construction and combination of after fully described and claimed, it being understood that various modications may be made in the minor details of construction Within the scope of the appended'claim. y.

Inthe accompanying drawings forming -part of this specification z-Figure 1 is a side elevation of my improved soldering iron.

Fig. 2 is a longitudinal sectional view through the soldering iron. Fig. 3 is a side elevation of the pump bulb. Fig. 4 is a side elevation of 'an eXtra soldering point. F 5 is a longitudinalr sectional view of a Vmodified form of the soldering' iron.

Referring noiv'to the drawings in which like characters of reference designate similar parts, 10 designates the combined hanand gasolene reservoir7 which is equipped at .one end with a` screw cap 1l having a pet cock l2 to which is attached a pump bulb 13 preferably of the type shown in Fig. 3. il. pipe i4 is threaded at one end into the head l5 of the reservoir, vand is provided with a nipple 16 upon which se'- cured a liexible tube 17 having' a weighted end 18. i

A yoke 19 is threaded on to the outer end of the pipe 14. and lthe branches of the yoke are equipped with screws 2Q through the instrumeifitalit-y1 of which a hollow copper soldering point 2l is secured. the soldering point being formed with the Ausual vent .openings 2.2.` The soldering point is thus y Specication'of- Letters Patent..
